JOSEPH T. THOMPSON, OF VERONA, NEW. YORK.

STOVE-GRATE.

SPECIFICATION forming part of Letters Patent No. 264,583, datedSeptember 19, 1882.

Application filed July 29, 1882.

To all whom it may concern:

Be it known that I, J osEPu T. THOMPSON, of Verona,in the county of0neida,'in the State of New York, have invented new and usefulImprovements in Stove-Grates, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to novel, simple, and effective devices forcleaning firegrates; and it consists essentially in the combiuation,withsaid grate, of a pivoted scraper liavng prongs or teeth entering theinterstices of the grate, and thus scraping the cinders and ashes fromthe top of the grate and effectually cleaning the same.

rIhe invention also consists in a novel construction and arrangement ofthe details of the aforesaid grate-cleaning apparatus, all ashereinafter more fully described, and specifically set forth in theclaims; 1

Referring to the annexed drawings, Figure 1 is a front view ofa tire-potand ash-box of a cook-stove. Fig. 2 is a vertical transverse section onlinex. Fig. 3 is a longitudinal section on line y y,- and Fig. 4 isanother vertical section, showing the gratein its dumping pol' sition. v

Similar lettersof reference indicate corresponding parts.

A represen ts the tire-pot of an ordinary cook-V hinge at its rearpreferably in a recess, r, in the back of the ash pit or box H, so as toshield the. hinged edge of the grate and prevent the ashes and cindersfrom entering between said edge of the grate andthe adjacent wall of thelire-pot. y

The front of the grates supported by a movable stop, e, which in theannexed drawings is represented in the form of a spring-bar, connectedat its lower end to the inner side ofthe end walls of theash-pit H, andhaving its upper end held yieldingly at a sufiicient distance from saidend walls to reach under and engage the bottom edges of the grate.

The grate G has interstices extending from rear to front and nearly theentire width ofthe grate, and forming a series of grate-bars, b b,

(No model.)

lunited at-tl1eir extremities. The greater or main portion ofthegrate-bar b, from the front rearward, is arched or of a segmentalcontour, as best seen in `Fig.2 ofthe drawings, and underneath the grateG the scraper-frame S is pivoted eccentrically in relation to thelsegmental part of the grate. The pivot of said frame is slightly forward.from the true center from which the segment of the grateG is described,for the purpose hereinafter explained.

The scraper-frame S is provided with a series of prongs or teeth, c a,Whichenter the interstices ofthe grate. One ot' the trunnions by whichthe scraper S is pivoted protrudes at the exterior of the ash-box H, andis adapted for the applicationof a wrench or shaker to its extremityforimparting the requisite oscillatory movement to said scraper, whichnormally lies back` against therear wall of the ash-box, and

has the extremities ofits teeth beneath the surand thus causes saidteeth to scrape the ashes..

and cinders from the top of the grate forward through the opening B.Inorder to render the aforesaid operation of the Yscraper moreel'ective, I terminate the scraper-teeth a with au abrupt front, @,and abeveled orf'curved back, d, thereby enabling said teeth to obtain abetter hold on theashesand cinders during the forward thrust ofthescraper and to pass under the ashes, 85e., during the backward movemeutof the scraper.

When it is desired to dump the grate the .stopse are removed from thefront ofthe grate, thus allowing the said portion of the grate to drop,as illustated in Fig. 4 of the drawings.

Havingdescribed my invention ,what I claim, and desire to secure byLetters Patent, is,

1. In combination with the grate G, thescraper-frame S, pivoted beneaththe grate and pro.

vvided with prongs a. a, entering theinterstices of the grate,substantially as and for the purpose set forth. y

2. The combination and arrangement, with the fire-pot A, provided withthe front openin g,

B, of the grate G, having arched bars b, and

. to the front of the grate,where they can escape the scraper-frame S,pivoted eccentrically in stop e, and the scraper S, pivoted beneath therelation to the grate-bars, and having prongs a a entering theinterstices of the grate., snb stantially as described and shown.

3. In combination with the grate G, the pivoted scraper S, having prongsa terminating with the abrupt front c, and beveled or curved backs d, asshown and described, for the purpose set forth.

4. The combination, with the fire-pot A, of the grate G, hinged at itsrear, the movable grate, all as described and shown.

In testimony whereof I have hereunto signed my name and aixed my seal,in the presence 15 of two attesting Witnesses, at Syracuse, in thecountyr ofOnoiidaga,in theStateof New York, this 22d day of July, 1882.
